Pull Request Overview

This PR fixes the issue of supporting variables as parameters in wxs methods by updating the filter transformation logic.

• Added a new code block to handle filter expressions by extracting and rewriting parameters.
• Introduced error handling for unsupported argument types in the parameter extraction.

Comments suppressed due to low confidence (1)

packages/uni-mp-compiler/src/transforms/transformIdentifier.ts:77

• Add validation to confirm that both '(' and ')' exist in contentStr before using them to extract parameters.

const paramStr = contentStr.substring(contentStr.indexOf('(') + 1, contentStr.indexOf(')'))

[Copilot]

Ensure that contentStr contains '(' before calling substring to avoid potential index errors if the character is missing.

Suggested change

	const lhs = contentStr.substring(0, contentStr.indexOf('('))
	const openParenIndex = contentStr.indexOf('(');
	if (openParenIndex === -1) {
	throw new Error("Expected '(' in contentStr but not found.");
	}
	const lhs = contentStr.substring(0, openParenIndex);

[Copilot]

[nitpick] Consider adding a comment to explain the purpose of this loop and why only the first non-space character after '(' is checked.

Suggested change

	let isLiteral = false
	let isLiteral = false
	// Check the first non-space character after '(' to determine if it is a literal object or array.
	// This is used to decide how to rewrite the parameters for the function call.
